(54) DEVICE FOR SUBMITTING ROLLS OF STEEL TAPE TO PACKAGING MACHINES

one

The invention relates to devices for laying out and packing rolls of narrow steel strip and is intended for use in the rolling industry.

A device for feeding rolls of steel tape to packaging machines is known, which comprises a frame on which a carriage with a lifting and lowering grip with rotating legs for passage into the roll hole and a storage table 1 located under the frame is installed.

However, this device has no pickups to improve the reliability of the grip and safe transportation of products.

The purpose of the invention is to improve the reliability of the capture rolls.

The goal is achieved by the fact that in a device for feeding coils of steel tape and packaging machines, comprising a frame on which a carriage with a lifting and lowering grip is installed, which has pivoting legs for passing into the bore hole and an accumulation table located under the frame radially relative to electromagnets for contact with the end of the roll are installed, the legs are interconnected by means of the toothed sectors, and drive cone rollers for the roll are mounted on the collecting table in. In addition, the legs are additionally interconnected by a power cylinder. The invention is illustrated in the drawings.

FIG. 1 shows a device, side view; in fig. 2 - the same front view; in fig. 3 - folding holders.

The coil feeder consists of

10 of the frame under which positioners 1 and 2 are installed, the first positioner is located at the head of the device, the second at the end. On the frame 3 there is a horizontal movement carriage 4 with a drive 5. 15 On the carriage 4 a pneumatic cylinder (lifting mechanism) 6 is installed vertically, on the rod of which there is a traverse with six electromagnetic grippers 7 having discrete and smooth adjustment of the lifting force from the electrical circuit. On the traverse 8, the folding legs are also mounted; the legs are clamps 9, made in the form of legs, which have a toothed sector 10 and an independent drive (pneumatic cylinder). A packing table 11 is installed under the frame.

with driven tapered rollers 12 and 13, which have a separate drive, activated by floor push buttons (not shown), rails 14 for supplying sliding carriages 15 and 16. Rails 14 are laid perpendicular to the longitudinal axis of the frame of the device.

The device works as follows

The bracket of an electric bridge crane of the rolls reel (where the outer end of the rolls removed from the drum of the longitudinal circular scissors winder and fixed) is placed on the head tilter 1, which turns the stack of rolls from the position with the horizontal axis to the position with the vertical axis of the rolls, the carriage 4 moves with the drive 5 along the guides of the frame 3 towards the head turner 1 and stops above the rolls 17. The traverse 8 is lowered down by means of the pneumatic cylinder 6, the electromagnetic grippers 7 are in contact with the upper roll om strips and draw her to her. The capture and lifting of the rolls is carried out with the help of six electromagnets, and depending on the mass of the roll or the foot of the rolls, the electromagnets are activated from a control panel (not shown) according to the established scheme: 2 cm. - opposite, 3 pieces - through one, 4 scht. - oppositely and 6 scht. - all at the same time. After lifting the coil with electromagnets, the folding holders 9 are moved apart; this is done with a view to safety when disconnecting the electromagnets. A roll or a roll of rolls is held by the inside diameter of the roll with paws, which are unclenched by the toothed sectors 10 from the pneumatic cylinder 18.

The raised roll is brought to the packing table 11 and smoothly lowered onto the first tapered rollers 12, where the second and third roll assemblies are made. The bound roll with the help of a lifting mechanism with electromagnetic grippers is placed on the second tapered rollers 13, where the rolls are packed into bags, after which the packaging and the connection of the rolls of the rolls are made. The packed pile of rolls is moved by a lifting mechanism to the tilter 2, where it is turned into a position with a vertical axis, then an electric bridge crane is transferred to the foot on the scales and to the finished product warehouse. If necessary, the packaging of the foot rolls on pallets used retractable trolleys 15 and 16.

The proposed device makes it possible to increase the reliability of the grip and the safety of transporting the rolls individually or in packages. Mechanizes the operations of transporting and rotating coils, relieves workers from heavy manual labor and increases productivity when laying out and packing rolls.
